Paper feeding mechanism for printer

Abstract

Disclosed is a paper feeding mechanism making it possible to reliably prevent deflection of the paper feeding roller and perform a stable paper feeding free from feeding deviation even when the paper feeding roller is formed as an elongated member. There is arranged a paper feeding roller and a plurality of press contact rollers held in press contact with the paper feeding roller, and there is arranged on the opposite side of the press contact rollers with respect to the paper feeding roller a support block which is held in contact with the peripheral surface of the paper feeding roller to support the paper feeding roller.

What is claimed is:  
     
       1. A paper feeding mechanism for a printer, comprising a paper feeding roller rotatable by a paper feeding motor, and a press contact roller held in press contact with the paper feeding roller and arranged in an axial direction of the paper feeding roller, recording paper held between the paper feeding roller and the press contact rollers, and a support block disposed on an opposite side of the press contact roller with respect to the paper feeding roller the support block being in contact at two positions with a peripheral surface of the paper feeding roller. 
     
     
       2. A paper feeding mechanism for a printer according to claim  1 , wherein the support block comprising a support roller rotatably supported and rolling while in contact with the peripheral surface of the paper feeding roller. 
     
     
       3. A paper feeding mechanism for a printer, comprising a paper feeding roller rotatable by a paper feeding motor, and a press contact roller held in press contact with the paper feeding roller and arranged in an axial direction of the paper feeding roller, recording paper held between the paper feeding roller and the press contact roller, and a support block disposed on an opposite side of the press contact roller with respect to the paper feeding roller, the support block having a support roller rotatable supported and rolling while in contact with a peripheral surface of the paper feeding roller.
